Smart Setup Registers
The meter uses three smart setup registers to configure all smar t input
modules. Input modules ISD1 and ISD2 require smart register 1 to be
set up, while input modules ISD3 and ISD4 require smart register 1
and smart register 2 to be set up. All four modules are single input sig-
nal modules with the choice of tw o channels. ISD3 and ISD4 also has
two solid state rela y (SSR) outputs dr iven b y SP5 and SP6 control.
SSR1 is controlled by SP5 and SSR2 is controlled b y SP6.
This setting enters the smart register 1 code
setup menu.
2nd digit settings 0 to 6 allows you to select input
signal 1 with a range of full scale voltage settings
from –
25 mV (setting 6) to –
2 V (setting 0).
Setting 7 allows you to select input signal 2 with
a –
1 V full scale setting.
Both input signals can accept < 60 V utilizing the
on-board 1:1000 atten uation header or e ven be
configured for a current shunt.

TIGER PROCESSING RATE
The following programming procedures co ver all the steps required to
configure ISD1 to ISD4. Steps 1 to 5 describe how to select the line fre-
quency rejection, the voltage range and input signal , and the out-
put rate through smart register 1.
Steps 6 to 9 descr ibe ho w to select the SSR (SR1 and SR2) output
mode f or SP5 and SP6 control through smart register 2 . Steps 10
onwards describe how to select the output register for channels 1, 2, 3,
and 4 as required.
Note, as ISD1 and ISD2 do not have SSRs, smart register 2 is not pro-
grammed.
Note:
The 1st digit setting is not rele vant to this
step. 0 is the default setting.

CH2, CH3, or CH4, a macro can reset CH1 b y
resetting register 253, CH2 b y resetting register
252, CH3 b y resetting register 251, and CH4 b y
resetting register 250.
2. As for Step 1, but using the LOCK pin to reset.
3. As for Step 1, but only applying to CH1 using the
